Patented May 19, 1931 UNITED STATES PATENT OFFICE JAMES E. ECKERSLEY, OFABERDEEN, WASHINGTON, ASSIGNOR OF ONE-HALF TO ALEXANDER POLSON, CFHOQUIAM, WASHINGTON SET WORKS FOB VJOOD CUTTING MACHINES Applicationfiled August 19, 1927; Serial No. 214,185.

The object of my invention is to provide a set worksfor wood cuttingmachines for such as a shingle, veneer, or shook machine, which by itsconnection to the block feeding rolls of such a machine, the block isfed toward the knife so that according to the setting the block willhave been fed forward more at one end than the other, and with this andother objects in view, my invention consists of the parts, andcombination of parts as will be hereinafter fully set forth.

In the drawings:

Figure 1 is a top plan view of set works embodying my invention.

Figure 2 is a front elevation of Figure 1.

Figure 3 is a side elevation of one of the clutch cases, part beingremoved.

Figure 4 is a side elevation of Figure 3, parts being removed and partsbeing in section.

Figure 5 is a side elevation of the clutch case with one of the sidewalls removed.

Figure 6 is a vertical sectional view through a clutch case showinganother em bodiment.

The reference numerals 6 and 7 designate standards in which are mountedbearing sleeves 8 and 9, said sleeves being held in position by means ofthe caps 10. These sleeves are revolvably mounted on the pedestals 6and7 and the ends of the drive shaft 11 are journalled within said sleeves.The sleeve 9 is provided at its inner end with the clutch member 12, andthe sleeve 8 is provided at its inner end with a similar clutch member13. A clutch member 14 is keyed to the shaft'll by means of the pins 15and extending from this clutch member 14 is a crank lever 16 which, inturn, is connected to a pitman '17 extending to a suitable source ofpower. I The shaft 11 is provided with a swivel connection 18 at one endconnecting the shaft lever 19 thereto whereby the shaft may be moved bysaid lever 19 into three positions so that the shaft may be held inneutral position, or where the clutch member 14 is not connected toeither the clutch member 12 or 13 of the sleeves 8 and 9, or the clutchmember 14 may be thrown in operative connection with either of theclutch members 12 or 13.

.20 and connected to the upper end of the lever .20 is a bell cranklever 21, the arm 22 of which is in the form of a' quadrant and providedwith an elongated arcuate slot 23 whereby the lever 21 may be adjustedto the desired position by means of the bolt and nut 24. Arod 25 isconnected by means of the pin 26 to the bell crank lever 21, theotherend of the rod. being connected to a clutch case 27, to be hereinafterreferred to, by means of the bolt and nut 28.

Mounted on the sleeve 8 is a lever 29 which is pivotally connected bymeans of the bolt and nut 30 to one end of the bell crank 31, the arm 32of which is in the form of a quadrant and is provided with an elongatedarcuate slot 33 whereby by means of the bolt and nut 34 the position ofthe lever 31 may be fixed. To the crank lever 31 I pivotally secure oneend ofthe rod 35 as at 36, the other end of the rod 35 being pivotallysecured to the clutch member 37. The clutch case 37 is revolvablymounted on the feed or transmission shaft 39, and on this shaft 39 andon feed or transmission shaft 40 there are also revolvably mountedclutch cases 41 and 42 and 27 which will be hereinafter referred to, the

clutch cases 27 and 41 being on the shaft 40' and maintained in spacedrelation by means of the sleeve 43 likewise mounted on the shaft 40while the clutch cases 37 and 42 are both aounted on shaft 39 andmaintained in spaced relation by means ofthe sleeve 43a mounted also onthe shaft 39.

Clutch devices 27 and 41 are one-way clutches constructed torespectively rotate the shaft 40 in opposite directions, and clutchdevices 37 and 42 are one-way clutches likewise constructed torespectively rotate the the shaft 39 in opposite directions, clutchdevices 27 and 37 acting to rotate the shafts 40 and 39 in acounterclockwise direction, while clutch devices 41 and 42 act to rotatethe shafts 40 and 39 in a clockwise direction. Clutch devices 27 and 42are coupled to sleeve 9 so that when said sleeve 9 is connected toclutch member 14 and shaft 11 oscillated shaft 40 will be turnedcounterclockwise by clutch de ice 27 and s aft 39 will be simultaneouslyturned clockwise by clutch device 42. On the contrary when sleeve 8 isconnected to clutch member 14 andshaft 11 oscillated clutch device 37will turn shaft 39 in a counterclockwise direction, while clutch device4L1 will turn shaft -l0 in a clockwise direction. The slotted quadrants22 and 32 permit the throw of rods anr to be varied on a working motionof shaft 11. while the quadrants ei and 50 permit the throw of rods 46and 52 to be correspondingly varied. It will thus be evident that thefeed roll actuating shafts 57 may be operated to actuate the feed rollsfor desired adjustii'ients of the ends of the block being ope ated upon.

The clutch case 27 is provided with a quadrant 4141 having an elongatedarcuate slot in which one end of the rod 46 is secured in anypredetermined position by means of the bolt or nut l7 to regulate thethrow of the rod 46, said rod being provided with a turn buckle 4:8 totake up slack in the rod. The other end of the rod 4-6 is connected bymeans of the bolt and nut 49 to the clutch case 42. Clutch case 37 inturn is provided with a quadrant 50 having an elongated arcuate slot 51in which one end of the rod 52 is fixed in a predetermined position bymeans of the bolt and nut 53. This rod 52 is also provided with av turnbuckle 53 and is connected at its other end by means of the bolt and nut5a to the clutch case 41, as clearly shown in Figure 2.

The subshaft 39 is connected at its inner end through a series ofuniversal joints 55 by the spline and sleeve shaft 56 to the feedrollers 57 of the machine, and subshaft 40 is connected at its inner endthrough a series of universal joints by the spline and sleeve shaft 56mto the feed roller 57a, which feed rollers may be like the feed rollersshown in 1y Patent No. 1,552,985 of Sept. 8. 1925.

Power being delivered through the pitman 17 and angle crank 16 to theshaft 11, then i through the bell crank lever 29, rod 85 to the clutch37, thence through the quadrant 50 of the clutch case to the bar 52 tothe clutch case 41.

As the clutch case 37 is operated clockwise for a given distance, clutchcase 41 is operating anticlockwise. but not as far as the clutch case 37on account of its quadrant connection to the clutch case 37, the line ofare being different.

Power being delivered to the power shaft 11, thence through bell cranklever 21, thence through the rod 25 to clutch case 27, and said clutch.case through its quadrant transmits power to the rodt6 to the clutchcase 41.

As the clutch case 27 is being operated for a given distanceanticlockwise clutch case 42 is operated clockwise. but not as far asthe clutch case 2. on account of its quadrant connection to the clutchcase 27, the line of are being different.

When power shaft 11 is operated for a given distance clockwise, clutchcase 37 will travel clockwise and clutch case ll will operateanticlockwise, both clutches turning the shafts on which they aremounted for a given distance, and when the clutch case ll is operatingin anticlockwise direction; and when clutch case 27 will be operatingclockwise, clutch case 1-2 will be operating anticlockwise.

Subshafts 39 and 4:0 deliver power to the feed rolls 5?, 57a of themachine through the universal joints and sleeve and spline shafts 55,56, respectively. If the block of wood in the machine to be operatedupon happens to be of more thickness at one end than at the other, andall thick butts should be cut from the thick end, then the set works maybe manipulated by shifting: power shaft 11 into either the sleeve 9 orthe sleeve 8 as the case may be. If, as in Figure 1, the clutch member1a is in engagement with the clutch sleeve 9 the action of the clutchcases would be as follows: clutch cases 27 and 4-2 would be operating onthe feed rolls and the clutch cases 37 and 41-]. would stand stationary.If the power shaft were to be moved in the opposite direction the clutchmember 14 would be in contact with the clutch sleeve 8 and would operateclutch cases 37 and 41 and they, in turn, would operate the shafts 39and t0, the clutch cases 42 and 27 not op erating.

The clutch cases have their own bearings on the shafts 39 and 10, beingloosely mounted thereon, but on the inside of each there is a mastergear fixed to the shaft.

Referring now to Figures 3 and 4: which is typical of all of the clutchcases, the master gear 58 is secured to the subshaft 40 by means of thekey 59. A clutch cam 60 is mounted on a suitable shaft 61 having aroller bearing 62 at each end thereof, the roller bearing being: mountedin recesses formed in the side walls of the casing. Said clutch cam hasassociated with it brake rolls 62 which are held in operative positionby means of the springs 63. These brake rolls are adapted to go intoclutchin engagement with the surfaces 6 1 of the brake ring 65 which ispressed into the gear case.

A pinion gear 66 is keyed to the shaft 61 and meshes with the mastergear 58. As shown, the clutch case is loosely mounted on the shaft 40,each side wall of the case form ing a bearing on the shaft on eitherside of the master gear 5 In Figure 6 I have shown a worm gear 67 asbeing substituted for the pinion 66, otherwise the construction is thesame as has been described in connection with Figures 3, i and 5.

It will be understood that my machine may be us d for cutting shingles,veneer and shooks.
